Installation Tips
1. The Model 720 Air Eliminator should be located in a clean, open area, where it is
easily accessible for inspection, service and repair.
2. The Model 720 Air Eliminator should be installed at the top of each air separator
(Figure 3-5), or it may be installed at the system piping highest point with a pipe
run from the air separator.
3. Additional Model 720 Air Eliminators are recommended for each component and
pipe locations where air could accumulate.
4. A shut off valve should be provided to simplify cleaning and replacement of float
and control assembly if necessary. Valve should remain open during normal
operating processes.
